PLANT FOR PRODUCING SHEET METAL BLANKS FROM LIQUID METAL BACKGROUND OF THE INVENTION The present invention relates to foundry machinery and more particularly, it relates to plants for producing sheet metal blanks from liquid metal.

The invention is best suited for manufacturing sheet metal blanks which can be up to 3-4 mm thick in iron-, nickeland copper-base alloys.

The present invention is also applicable to the production of plate metal blanks which can be up to mm thick in aluminum-iron-base alloys.

Commonly known are plants for producing sheet metal blanks from a liquid metal comprising a pouring device, a receiving-distributing device, rolls for crystallization of the liquid metal into a strip and a strip remover.

The known plants are subdivided into two types depending on the kind of blanks produced sheets'or SUMMARY OF THE INVENTION The present invention has the objectives to develop a plant for producing plate metal blanks from a metal in the hot fluid state with the capabilities of the blanks both in strips and in sheets said invention being additionally compact and simple in operation.

The objectives of the invention are achieved in a plant for producing sheet metal blanks from liquid metal comprising the following devices mounted in the direction of technological process: a pouring device, a receiving-distributing device, rolls for crystallization of a liquid metal into a strip, and a strip remover which plant conforming to the invention is further fitted with a device for cutting the strip into sheets, a sheet conveying device, a sheet piler and a strip coiling device.

In order to improve the feeding the sheets into the sheet piler, it will be expedient to make the sheet conveying device in the form of a chain conveyor having a speed which exceeds the speed of rotation of the rolls and which is high enough to transfer the sheets to the piler.

Where the proposed plant is to be used for producing blanks in the form of a continuous strip, it would be sound practice to make the sheet conveying device composed of two chain conveyors either of which is arranged to swing in a vertical plane having a drum of the strip coiling device mounted there between.

Wherever the proposed plant herein is intended for producing blanks in the form of sheets it would be sound practice to mount the device for cutting the strip into sheets in the direction of the technological process between the strip remover and the sheet conveying device.

To keep the strip from damaging in downending and coil stripping, when the proposed plant is employed for fabricating blanks in the form of a strip, the strip coiling device shall comprise a fixed baseplate and a housing incorporating a drum for reeling the strip into a coil, a drum rotating drive and a coil ejecting mechanism with the housing being arranged to swing in a horizontal position during coiling and in a vertical position for removing the coil.

To facilitate and simplify the removal of the coil from the drum, it would be expedient to make the coil ejecting mechanism in the form of a pusher which passes inside a drum shaft along its axis of rotation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 1 A plant for producing sheet metal blankscomprises a pouring device 1 (FIG. 1) which serves for mounting and tilting, a pouring ladle 2 filled with liquid metal, a receiving-distributing device 3 with the function of feeding the metal in a hot fluid state to rolls 4 where it crystallizes into a strip, a strip remover 5 (FIG. 2) arranged under rolls 4 and designed to direct the moving strip, a device 6 (FIG. 2) for cutting the strip into the sheets, a sheet conveying device, sheet piler 7for piling .and stacking the sheets, a device 8 (FIG. 2) for reeling signed for crystallization of the liquid metal into a strip 7 said rolls also being mounted on frame 11 and rotating from an individual drive 12. A primary function of strip remover 5 arranged under rolls 4 is to alter the direction of a formed strip by turning it from a vertical position as it emerges from rolls 4 to a horizontal one, which is necessary to transport it further in the unit.

The sliding track of strip remover 5 is smooth enough to eliminate the strip from braking during its travel.

Device 6 for cutting the strip into sheets is mounted in the direction of technological process which is afterstrip remover 5 and represented by drum-type shears which serve for subdividing a newly formed strip into sheets of a requisite length. The latter can be changed by adjusting the speed of rotation of a shear drive. Rotatable holders 14 of the shears on which blades 15 are secured can be spaced apart to obtain a gap adequate for the free passage of the strip. This is necessary in order to allow the strip to pass freely in the above gap with the shear drive cut-off to be further reeled into a coil.

The sheet conveying device is a chain conveyor having a rate of travel exceeding rotational velocity of rolls 4 and being high enough to transfer the sheets on sheet piler 7. It is necessary on the one hand that the strip being formed does not crawl over the cut-off sheets during their conveyance to a piling site, and on the other hand, it is necessary to avoid damage to the sheets dropped at the instant they are piled. The aforesaid conveyor is made up of two branches 16 (FIGS. 2 and 3) and 17 either of which is arranged to swing in a vertical plane.

The branches 16 and 17 are brackets either of which is secured at one end accordingly on axles 18 and 19 with aid of hydraulic cylinders 20.

Axles-l8 and 19 of the brackets are mounted on supports (not shown in the drawing) said support being,

attached to frame 21 of the unit. On one side of each hydraulic cylinder 20 of the drive of slewing conveyor, branches 16 and 17 are articulated with the branch bracket and the other side is disposed with frame 21 of the unit.

Vertical position or mode of the first branch 16 in the direction of movement of the strip enables the forma tion of a compensating loop by virtue of which the strip is called without tension, the second branch 17 being placed in an upright position or mode to provide free space for device 8 intended for reeling the strip into a coil.

The device (FIG. 4) for reeling the strip into a coil consists of a stationary baseplate 22, a swivel body 23 which mounts on drum 24 for reeling the strip and drum rotating drive 25.

The foregoing device 8 is arranged after device 6 for cutting-the strip into lengths with baseplate 22 being slightly misaligned in relation to the longitudinal axis of the unit and secured on its frame 21. Due to the above arrangement of'device 8 for reeling the strip into a coil the body 23 with drum 24 can be placed in a horizontal and vertical position. The aforesaid device 8 is designed for coiling the strip, by turning the coil into a vertical position without causing damage to it and for ejecting the coil from drum 24.

Body 23 of device 8 is mounted on baseplate 22 with the aid of trunnions 26 having ends with toothed sec tions (not shown in FIG. 4) rigidly fixed thereto. Each sector is in mesh with a toothed rack (not shown in the drawing) having ends act that as pistons of a hydraulic cylinders 27 (FIG. 4).

Hydraulic cylinders 27 fixed rigidly on stationary base plate 22 of device 8 are designed to swing the said body 23, placting it either in a horizontal or in a vertical position.

One end of drum 24 of device 8 is mounted on a shaft 28 fastened with the aid of rotating supports 29 in body 23 of device 8 and rotated by drive 25 coupled with shaft 28.

The other end of drum 24 rests on revolvable swivel disc 30 (FIG. 5). This occurs only when drum 24 is in Pivot 31 of swivel disc 30 and hydraulic cylinder 32 i are set up on base 33 which is fixed rigidly on frame 21 of the unit.

Mechanism 9 for ejecting the coils from the drum 7 I comprises pusher 34 which passes inside of shaft 28 of drum 24 of device 8 along its axis of rotation. One end of pusher 34 is rigidly connected with a rod of hydraulic cylinder 35 of a mechanism drive, while the other end is coupled to cross arm 36 which is arranged in slots 37 of drum 24 and strikes against the coil at the instant of its removal from the drum.

Sheet piler 7 constitutes table 38 coupled with a rod of hydraulic cylinder 39 with its function being to raise and lower the table and to press the sheets piled on the table. Table 38 is limited from four sides by vertical walls 40 and on top of sheet piler 7 there is swivel plate 41 which is set up on independent stand 42 fitted with an individual drive (not shown in the drawing) and use for pressing the sheet pack. 1

The proposed plant herewith functions as follows Ladle 2 of pouring device 1 filled with liquid metal is in a lower position;

Rolls 4 for crystallization of molten metal clamped to each other are rotating;

Holders 14 of blades 15 are stopped in such a position so as to provide a gap between them which is adequate for free passage of thestrip;

In themotional direction of the strip the first conveyor branch 16 is placed in a horizontal position and is rotating with the other branch placed vertically and remains motionless;

Body 23 of device 8 in conjunction with drum 24 is placed in a horizontal position, slot 37 of drum 24 also being located in a horizontal plane;

Swivel disc 30 is shifted towards drum 24 and coupled thereto.

On tilting ladle 2 of the pouring device 1 liquid metal is admitted into receiving-distributing device 3 then it is directed in a roll gap or interroll space of rolls 4 where the metal crystallizes and is formed into a strip. Next, the formed strip is directed by means of strip remover 5 into a gap between holders 14 of blades 15 then it is passed in the motional direction of the strip to the first horizontal slewing branch 16 of a conveyor which serves to feed the strip in drum slot 37.

After the front end of the strip has moved some distance, behond slot 37 of drum 24, the drum rotating drive 25 is switched on. The length of the strip end issued from the slot prior to drum rotation will ensure reliable grasping of the strip.

As soon as the drum of device 8 starts rotating, the

the coil is placed in a vertical position. Then coil ejecting mechanism 9 is engaged into operation.

Hydraulic cylinder 35 raises the coil a little with the aid of pusher 34 and cross arm 36, whereupon shop handling facilities can remove the coil completely'from the drum. The mechanisms are now returned to their initial positions.

The unit functions in the following manner when it is used for producing metal blanks in the form of sheets.

All the mechanisms and devices of the unit are placed in the same initial positions as in making strips except that:

The shears are switched on and holders 14 of blades 15 are rotating;

The second conveyor branch 17 is positioned in a horizontal position with the two branches forming a single continuous conveyor;

Drum 24 of device 8 is set to a vertical position.

During the forming, the strip directed by strip remover 5 is passed to the shears where it is cut to specified lengths; the cut-off sheets are taken up by a conveyor having a speed slightly greater than that, of the strip being formed. Then the sheets are transferred to a sheet piler to be stacked in a pack.

As the ladle is emptied, the sheet pack produced is pressed by raising table 38 and forcing it against the piler swivel plate 41 in order obtain a tighter pack which is convenient for further treatment.
